Image tool

Image Compressor

Reduce the file size of JPG, PNG and WEBP images with quality control.

100% local — files never leave your deviceProcessed in your browser

How it works

Drop one or more images.
Pick a compression preset or enter an exact target size (e.g. 100 KB).
Compare before/after sizes and download.

Good to know

Screenshots and flat graphics are protected with higher quality floors than photos, so text stays legible.
JPEG has no transparency — converting a transparent PNG to JPEG fills transparency with white (the tool warns you).
Every step runs locally in your browser using Web Workers — your file is never uploaded to any server.

Frequently asked questions

How small can an image get?

Depends on content. Photos tolerate strong JPEG re-encoding; screenshots and logos need higher quality floors. Target-size mode finds the best quality that hits your number.
